Lining for window channels

Patented Oct. 27, 19136l urmrral) STATES' .PA-TENT'I oFFlcE This invention relates to certain improvements on, `or a modified formof the particular type of lining for window glass channels shown in my pending application Serial No. 60,783, filed J anuary 25, 1936, said type being in the form of a lining for the sides of a deep channel, in which cushion-.-

ing means f or the edge of the glass is not necesfsarily provided.

The objects of .my present invention are to pro- `vide a form of lining, Iweather or cushioning strip,l of the type above referred to, which will Vpresent a finished appearancewhen installed, which is adapted to be bent to correspond to-'the curvature of the window frame in which it is to be installed, which will provide an effective cushioning means for the glass and which is particularly well adapted to be produced commercially in large quantities at a minimum expense.

I accomplish these objects by means of the construction hereinafter described and as illustrated in the accompanying drawing, in which: Fig. 1 is a combined sectional and perspective View, on an enlarged scale, of a lining or weather strip embodying my invention.

Fig. 2 isv a sectional View of a deep window glass channel, to which an embodiment of my invention has been applied.

, Fig. 3 is a detail View in perspective of the core` which is employed.

Fig. 4 is a combined side elevation and longitudinal sectional View illustrating the formation when bent.

V Fig. 5 is a detail sectional view at line 5-5 of Fig. 4. f

In the drawing, Fig. 2 illustrates in cross section'a window casing a, having a common form of deep channel, to the sides of which an embodiment of my invention is applied.

According to my invention I provide a core which consists of a strip of thin sheet metal b. which is transversely slotted from one edge at regular intervals, to provide a series of regularly spaced tongues c, the width of the spacing being equal to the width of the tongues, so that two strips Amay be cut from a single somewhat wider strip without waste of material. `The continuous edge portion thus formed is bent reversely, or rolled, to provide a cylindrical edge portion d, and the end portions of the tongues are bent at right angles, alternately in opposite directions,

'forming alternately disposed end flanges e. A

strip vof cloth f, or backing isprovided onwthe bottom side of the core, one edge portion of which extends over the edges of the inturned end flanges e of the tongues, as shown in Fig. 5, and

the opposite edge portion of the strip is extended about the cylindrical portion d and between the edge thereof and the side of the core adjacent thereto. A cushioning strip g of velvet, or other tufted material, is provided on the top side of the vcore and is so arranged that one edge portion thereof extends over, and is engaged by the edges of the out-turned flanges e and the other edge portion extends beneath the corresponding edge portion of backing f. Both of the latter edge portions are then firmly clamped between the edge of the cylindrical portion d and the adjacent side of the core, as shown in Fig. 1.

A shim strip h, or supplemental cushioning strip, which consists of a narrow strip of felt, or thick cloth, is placed between the core and the vcushioning strip g, and a bead z', of ornamental i the strips f and g in position on the end portions` of the tongues, while, at the same time, it permits the slight movement of the tongues' relative to the bead which is'necessary to permit bending of the entire strip sufficiently to conform to the ordinary curvatures of the Window frame, as indicated in Fig. 4. The force with which the bead is clamped, which is suiiicient to hold the strips f and g in position on the ends of the tongues, and yet permits the slight movement of the tongues relative to the bead necessary to bending, has been determined by careful experiment.

While the reenforcement of the cushioning effect of the cushioning strip may be secure by at-g taching a supplemental strip of cushioning material to the outer side of cloth strip, as shown in my said prior application, the arrangement of a shim strip between the velvetstrip and the core is particularly advantageous for several reasons. The shimv strip is held in position without employing any particulars'ecuring means, the expense for the Vwork of the stitching operation and the expense of thread being avoided. Also stitches reduce the cushioning effect of the pile of the velvet, as the stitches cause a portion of the pile less expensive than a fabric having a longer pile. 56

1 As thus arranged the assembling operation may be automatically performed very rapidly, so that the labor costis substantially reduced.

When the `finished strip is installed, vthe back side of the strip is` placed against the garnish moulding in such a position that the shoulder formedby the metal bead bears against its outer surface, so that the bead projects beyond the moulding and forms an ornamental nish, as shown in Fig` 2. In like manner the strip is usable at the bottom of a window opening.

In practice it is frequently necessary to cut the strip obliquely, and for this reason it is particularly desirable to have both edges of both the back and cushioning strips securely clamped to the metal core, as otherwise the pointed portion left by the oblique cutting would be likely to become loosened and fall away from its position in the bead.

I claimt 1. A window glass Vchannel lining having a core consisting of a strip of sheet metal having o ne edge portion continuous and bent reversely to form a beaded edge and having a series of equally spaced tongues extending transversely from said edge, the end portions of said tongues being benttransversely to form oppositely disposed flanges, a -Ll-form metal bead mounted on the ends of said tongues, and textile backing and cushioning strips on the back and face sides, respectively, of said core, the edge portions of said textile strips at one edge of said core being clamped by said bead against the opposite sides of said tongues, and the opposite edge portions of said textile strips being clamped between the edge of said reversely bent portion of the core and its adjacent side, the clamping action of said bead being adapted to permit a slight relative movement of said tongues therein when the 40 strip is bent.

consisting of a strip of sheet metal having one of its edge portions continuous land bent reversely to form a beadededge and having a series of equally spaced tongues extending transversely therefrom, the edge portions of said tongues being alternately bent oppositely to form oppositely disposed' flanges, a U-iorm metal bead enclosing the end portions of said tongues, and textile backing and cushioning strips on the back and face sides, respectively, of said core, the edge portions of said strips at one edge of said core extending yover the opposite edges of said flanges respectively and being-clamped thereagainst by said bead, and the opposite portion of the backing strip extending about said reversely bent edge and having its edge portion and the adjacent edge portion of the cushioning strip clamped between the rever'sely bent portion of the core and its adjacent side, the clamping action of the bead being adapted to permit a slight relative movement of the tongues therein when the strip is bent.

3. A window glass channel lining having a core consisting of a strip of sheet metal having one edge portion continuous and bent reversely to form` a beaded edge and having a series of equally spaced tongues extending transversely from said edge, the end portions of said tongues y being bent transversely to form flanges, a. U-form metal bead enclosing said ilanges, textile backing and cushioning strips on the back and face sides, respectively, of said core, the edge portions thereof at one edge'of said core being clamped against said tongues by said bead and the opposite edge portions of said strips being clamped between the edge of the reversely bent portion of the core and its adjacent side, and a supplemental cushioning strip disposed between the core and said cushioning strip, the clamping action of said bead permitting a slight relative movement of said tongues therein when the strip is'bent.
